<p>And which version the <em>com.liferay.gradle.plugins.workspace</em> is using inside <em>settings.gradle</em> in your workspace? Have you updated it? </p>

<p>Any leads?</p> <p>Also, I have tried by changing the JDK, and using 7.4 GA105 to build.</p>

<p>Which DXP version are you using?</p> <p>You can see in your $Liferay_Workspace/gradle.properties the value configured in the property -&gt; <strong> liferay.workspace.product</strong> </p> <p> </p>
